Detectives have been given a 28-hour extension to continue questioning a man over the Clydach murders.

Detectives have been granted a 28-hour extension to continue questioning a man over the murders of four members of the same family.

David Morris, a 38-year-old scrap dealer and labourer, has been held by senior detectives since 7am on Tuesday when police arrested him at the Swansea Valley home he shares with his girlfriend Mandy Jewell, 32.

Mr Morris was taken to Swansea Magistrates' Court at 5.30pm on Wednesday where police asked for more time to question him.

After the magistrates allowed an extension of 28 hours to continue questioning Mr Morris, he was driven to an undisclosed police station for a further series of interviews about his movements on June 27, 1999, when the women and girls were killed.

Mr Morris's home in Craigcefnparc is about a mile from the Clydach house where the mutilated bodies of 34-year-old Mandy Power, her 80-year-old disabled mother Doris Dawson and Mrs Power's children Katie, 10, and Emily, eight, were discovered by firefighters.

Police had been granted an extension of 12 hours to continue questioning a 32-year-old woman arrested on suspicion of attempting to pervert the course of justice. She has been released on bail.
